Developmental time, longevity, and lifetime fertility of three previously introduced parasitoids (Acerophagus papayae Noyes and Schauff, Anagyrus loecki Noyes and Menezes, and Pseudleptomastix mexicana Noyes and Schauff) (Hymenoptera: Encyrtidae) of the mealybug Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) were studied in the laboratory to understand the outcome of their recovery in field studies conducted in the United States. The developmental time of both male and female A. papayae and A. loecki was shorter than the developmental time of male and female P. mexicana. Male parasitoids of all three species had a shorter developmental time than …

The southern chinch bug, Blissus insularis Barber, forms dense, multigenerational aggregations in St. Augustinegrass lawns leading to grass death from sap feeding. We conducted laboratory bioassays to better understand the signals responsible for the formation and maintenance of southern chinch bug aggregations. In small arena assays, chinch bugs demonstrated a stronger aggregation response over time and aggregated more often on or beneath St. Augustinegrass leaf blades than on or under artificial leaf-like shelters constructed from white or green paper. In Y-tube olfactometer assays, bugs of different age and sex were attracted to volatiles from mixed-sex chinch bug aggregations and showed …

Most Hedychium J. Koenig (Zingiberaceae) species have showy and fragrant flowers, which are used in leis and perfumery. Hedychium species are easy to grow and are mostly free of major diseases and pests. The essential oils of some species have been found to have insecticidal, antibacterial, and antifungal activities (Gopanraj et al., 2005; Jadhav et al., 2007; Medeiros et al., 2003). Hedychium plants prefer moist, fertile soil and are considered to be shade plants but will thrive in full sun if provided adequate moisture, and many species will grow and bloom throughout USDA zone 7 (Adams, 1999). Hedychium plants are …
